same, reference being had to the accompanying drawings, and td'theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates broadly to the class of heating devices forautomobiles and further contemplates the provision of a device of thischaracter which is simple in construetion, strong, durable and eflicientin operation and one which can be manufactured and. placed upon themarket at a minimum cost. 7

By using the exhaust gases from the engine as a heating medium it isapparent that the cost of operation of the device reduces -it to aminimum and that its provision upon ..a vehicle will not cost any greatexpense to the owner thereof. It will also beapparent from'thehereinafter ap caring description that my device will so e thesubsidiary function of a mufiier, it receiving directly tihe exhaustgases from the engines cyliners. a While I'have designated in thedrawings suitable exhaust gas passages and suitable water passages, itis to be realized that water may be introdu'ced through the gas pas- Jsages and. the gases through the water pas- 40 sages if such occasionpresented itself.

', With the above and other objects in view' my invention consists insuch details of construction and in the varrangement and combination ofparts as will be hereinafter more fully described and specificallypointed out in the appended claim. In desc" 'bing my invention in detailreference will behad to, the accompanying drawings wherein likecharacters denote like or corresponding parts'throughout the severalviews, andin which 2 I Figure 1 isa perspective view of my invention;Fig v 2' is a; sectional view oniline 22 of Fig. 3, and Fig. 3 is asectional yiew on line 33 of Fig. 2. 1 Reference now'bein'g-had to thedetails of respectively inner and outer concentrically arrangedcylinders spaced apart from each other and intermediate thesame are lugs16. Each end .ofthe outer cylinder is provided with an opening, onebeing an inlet opening through which a pipe 20 passes and the other anoutlet opening from whichan exit p pe 25 leads. Said outer cylinder isprovlded with acircumferential covering 15 of insulating material, andabout the latter s a covering of metal 15". Theinner cylinder 14 isprovided with a transverse partition 1'8near one end soas to, form achamber 18 Said partition is perforated for the reception of the openended fiues 19, which at their opposite ends are mounted in perforationsin one end of the inner cylinder..

jacent ends of the inner and outer cylinders,

asshown in Fi s. 1 and 20f the drawings. It will be note that the endsof the tubes 19 are open and are adapted to receive exhaust gases whichare conducted through the pipe 20 to the chamber 18 formed intermediatethe perforated partition engaged by said pipes 19, and the adjacent endof the inner drum. A pipe 39 passes through the wall of the outercylinder and eommunicates with theinterior of the inner drum. Water,which is preferably driven by a pump, is

.forced through the pipe 13 into the interior of. the shell 14 andbecomes heated by contact with the flues 19 and makes exit through thepipe 39 leadinfrom the upper portion of the shell 14 an" through thewall of theshell15. i m

The hotwater, after passing from the shell 14, passes through ipe.19 bythe valve 40, pipes 38, 33 34: an 35, thence by the union 37 and thepipe 36, thence through the union 37 and pipes 33, 34; and 35, throughthe elbow 32 and pipe 28, through thevalve to the connection 27 andthrough the pipe 26 back to the pump, thus making a comlete circuitl Thegases, after g1ving ofi heat by radiation, make exit throu h thepassageway 25 to the atmosphere. f funchamber 30, regulated by the valve29, thence ml 29 communicates with the yalvecham ber 30, regulated bythe Valve 29. The

Valve 29 serves to regulate the flow of water through the pipe 28 anda-suitable faucet 31 is fitted to the pipe 28 through which Water may bedrawn from the latter. A pump 12 is mounted upon the shaft 7 in suitablebearings upon the depending bars 3 which are fastened to the frame 1 anda gear wheel 12', driven by a gear wheel 11 fixed to the shaft 6- uponthe hanger 3, fastened to the frame. The shaft 6 has a bev- ,eled wheel10 in-meshwith the gear wheel 9 upon the shaft 8, whereby power issupplied to operate the pum What I claim to be ne izv is In combinationwith an outer and an inner cylinder, lugs intermediate the-cylinders andspacing the same apart, an apertured partition in the inner cylinder, apipe passing through the aperture in said partition and through one endof both the inner and the outer cylinders, a series of.openended fiuespositioned within the inner cylinder and extending through aperturesformed in one end of the latter and the partition therein, a'partitionwithin the outer cylinder having a central opening, a baffle platewithin the outer cylinder adjacent to its end spaced apart therefrom, anexit pipe leading from the end of the cylinder adjacent to the baflleplate, and an inlet pipe and an outlet pipe, each communicating with theinner cylinder, as shown and de scribed.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
